“We have determined that the truck recovered in Gold Bar was not involved in the collision,” Willis said Friday.

Through video surveillance, police have identified the vehicle. It is believed to be a late 1980s to early 1990s Ford F-series pickup. It’s thought to be white with dark blue or green stripes.

The Monroe Police Department is seeking any additional witnesses to the collision or any event leading up to the collision. They are asked to call 360-794-6300 or an anonymous tip line at 360-863-4600.
